To all whom it may concern:

Be it known that I, EDWARD R. STOWELL, a citizen of the United States, and a resi- 35 cate with the free silicon or silicon compounds contained in the carborundum, the said formation being hydrogen gas. When packed in sealed containers th1s"'gas will either explode the container, causing loss of contents, or escape with considerable force when the container is unsealed. To prevent this the mixed composition is placed in an ample container, filling same but one half full, covered but not air tight, and subject- In testimony whereof I have signed my name in the presence of two subscribing witnesses.
